The easy button
to build your Backend
A developer-first PaaS alternative to Heroku, Railway & Render that gives you simple deployments without giving up infrastructure control. Host with us or bring your own cloud or servers.
Why ModStack?
Any Language. Any Framework. Any Cloud.
Write in the language you love — JavaScript, Python, Java, Go, or anything else. Use any framework. Deploy to any Kubernetes cluster — EKS, GKE, AKS, on-prem, or bare metal. ModStack gives you the power of a managed PaaS without locking you into a single vendor or stack.
